This invention relates to improvements in weft replenishinglooms and it is the general object of the invention toprovide an improved form of brace'which can be inter posed between the'magazine and apart of the loom capable of assuming several different positions.

r In Weft replenishing looms the'magazine' ordinarily derives its main support from a loomside and derives additional support .froma connection to the arch. Where a loom isbuilt to weave a single type of fabric, such for instance as gingham, the arch will always remain in the same position with respect to arch. There areinstances, h owever,*where it is deslrable to employan-arch which can assume 'chfierent POSltlOIlS, as for instance,

when it is desired to shift from onetype offabric to another,'and'it.isan important objec't of my present invention to provide a brace which can be interposed between the magazine and the arc-h irrespective'of the position of the latter, the bracebeing efiective' in all positions of the arch to steady th magazine. 1 V

atively forward, position nearthe magazine.

If the same loom is to be used for weaving a ,moreelaborate fabric, however, it "may be necessary to employ four or :more harness frames, in which case. the arches 'will'be moved rearwardly to accommodate the added 'It is desirable that the inside -plate of the magazinebe made as compactl s possiblel' The usual brace ordinarily extends'from an arm of the magazineto the-arch, 'liutginas' much as movement of the latter may be -a matter of several inches 'to a'ccommodate harness frames of different numbers it isdesirabletoconstruct. the; brace ,so that the the loomside, so that a one-piece brace may" be interposed between the magazine and the" magazine arm' needEnotIbe too iagx'r a may-gbe doneiinisuch away as to provide a ,coa-rse or"steppedadjustmenttogether with finer or continuous adjustment provided on "the, arm of'the magazine. 1 In this {wa the arm can be kept small enough so that it-willnotinterferewith 'the'arch when the latter was in its foremost: position.

The loomsidehas annp'per raillawhieh is providedwitha slot 16 through which ex tend bolts 17 There is mounted on the rail an arch 18 through which the bolts l7pass. The rail extends substantially horizontally so that'the' archj-may be attached thereto'infi aplurality of positions at diiferent distances" preferably with zonta ly extend from the breast'beam and magazine. "It is to-be-"under stood that in the case offsimp'le I 9. e

fabrics the arch will be relatively close to'the breast beam, whereas if more harnesses are employed the arch will be moved rearwardly. v By referring to Figzl it will be seen that the magazine has a foot 19 which is held to the loomside by means of bolts 20 so that theforward end of the magazine is attached to fixed structure and is held in position irrespective of the position of the arches.

,This is necessary in order that proper delivery may be made of the full bobbin into an empty shuttle. V

' The iniatter thus far described is of common construction and of itself forms no part of my present invention, the magazine being if desired of the form No.-1,030,748. a

In order to brace the magazine from the arch I provide in the preferred form ofthe invention, a two-part bracket including an arch supported member-3U held to the arch by a bolt 31. This members is provided with a substaiitially vertical toot 32fwhich is held in e ge 'einent Preferably with the ti n falc 3361 the ar ch, Said arch I lQII ber3O is prov ded with a horizontally extending arm in which is located a relatively long narrow slot 35. Tllelieisentending through said slot a bolt 36 having a head, 37 on the lower endthereof with a nut 38, at the upper. end where may be readily reached for adjustiiig purposes The under surface of, the arm .35 is provided with corrugations 39 which b er 42.

shown in prior Patent to suit the ina azine. After the arch is in its new position the'nut 38 may be tightened, this operation being accomplished in all likelihood by a slight shifting of the brace members due to the fact that the corrugations do not permit a continuous adjustment but permit only a stepped adjustment. Any slight motion of the magazine member or" the brace produced by the interengagement of the cor rugations 39 and 40 will be permitted by the slot 45, so that after the nut 38 is tightened the nut 4? ma also be tightened. It is to beunderstood that the adjustment permitted by the slot 45 will be equal at least to the distance between successive corrugations on either or" the arch or magazine members.

It will be understood that inasmuch as the magazine must remain fixed with respect to the lay not shown in order to effect correct transfer of a full bobbin, and inasmuch as the arches are. located by the harnesses, it is necessary to, effect a connection, between these two independently and arbitrarily placed members and this adjustment should; be continuous. moying the brace members with, respect to' each other a rough or approximate or stepped ad ustment can be secured, atterwhich the finger or continuous adjustment can, be efiecteclby the slot 45. In this wayv the. brace. may act merely as a connection between the. magazine and the arch withput subjecting either to a strain imposed the other.

v While. I have stated that only one of the slots in the magazine member of the brace is necessary, yet by a, modified construction, a foot: similar. to foot 43; may be provided with a. hole only suificiently largeto accommodate. the bolt 46, and a slot 50 may be.

formed in an arm 51: as shown in Fig. 3. It is sufficient, for the purposesot my present invention. to beableto effect an approximate orstepped adjustment betweenthe arch members and, then be able to effect a finer continuous adjustment betweenv the clamp members and either thearch orthe magazine. As

shown herein the fine adjustment iseffected at the magazine end of the-brace, and it is to, facilitate this adjustment that the foot 43 rests upon the horizontal upper surface of the arm 13. i

From the foregoingit will be seen that I ave vprovidedl a very simple means for adjustingv the bracebetween the magazine and the movable arch of; a loom. It will further be e ithat hebre s s made 1 a'fiord an approximate adjustment between the brace members and a finer; adjustment betweenone of; the bnacemembers and the magazine. Itwill; be seen more broadly that I have provided arch and magazine elements which'are connected together by a brace formed; of; members having a stepped coarse adjl sti 'nt,v said memb rs. being capable when approximately adjusted to their cora g 1, 5 '5 I,

tinuous adjustmentbetween the'magazine Gil one of the elements so that neither the arch elements will-be subject-ed to or magazine strain.
